Determine the time it takes for a satellite to orbit the moon in a circular "near-moon" orbit. a "near-moon" orbit is at a height above the surface of the moon that is very small compared to the radius of the moon. [hint: you may take the acceleration due to gravity as essentially the same as that on the surface.]
